Not nearly enough info to go on in the auction description, but the 'dusty car in the garage' look makes it intriguing enough to reach out to the seller.
Unfortunately, since it's NOM, it will be a tricky one to document.... It has had some '69 Z mods over the years, including engine and hood - hard to tell how it was originally configured.
